FOCUS ON EC FAN ONLY
PBM FOCUS ON EC FAN ONLY. Certificate: CE,UL,ROHS; Supply Ability: 100,000 pcs per year; MOQ: 1~100 pcs based on EXW price; 100 pcs above based on FOB price.
250mm EC Centrifugal Fan with Support Bracket fan made especially for Dialysis Device; Hemodialysis System is the PK3N250B2EL. It is often utilized in hemodialysis machines' internal cooling systems. The high-power power modules, control units, and sensors inside the equipment continually produce heat during the four to six hours that hemodialysis treatments usually endure. As the primary active cooling unit, the PK3N250B2EL uses forced air circulation to quickly disperse heat from the machine, guaranteeing precise dialysate temperature control and steady treatment parameters. It provides core power for a variety of blood purification devices with a high static pressure of 690 Pa and a large airflow of 1290 m³/h. It is also appropriate for airflow units in centralized dialysate supply systems, positive pressure ventilation and negative pressure extraction modules in dialysate circulation systems, and multi-chamber airflow distribution in CRRT (Continuous Renal Replacement Therapy) equipment.
PPM supports OEM customization services by concentrating on the development and production of superior EC/DC fans and intelligent airflow solutions. Product designs have earned reputable certifications including CE, UL, and RoHS and adhere to worldwide medical safety standards.
